The A Spot is the Anterior Fornix. It’s located up inside her vaginal canal and there’s some confusion as to where exactly it is. Because every day is a new day, women like different strokes to match their body’s mood. Once she’s very lubricated (you can use an organic, natural oil like Avocado Oil) and engorged from your foreplay stimulation, you can start stroking deeply up inside her, beyond the G-Spot and see what she responds to.
Don’t worry about the “perfect” spot, because it’s a moving target. Just stimulate and watch and listen for her feedback. Also, feel what feels good and sexy to you, and she’ll probably like that too.
